Application filed February 24:, 1908. Serial No. 417,273.;

To all who: if mdg/ r'om'rrn: Be it known thzu wry-Joni; lip'rniisosnnd 1 l lClIGHSUN. (ll'lZCIlS of the numerous tr. l mited ftitzues, oud residents of Detroit, in l the rountjt oi liar-yin and State of h'licliin un, hsw invented new and improved llxplosimi-i 'lngginr oi whit-h the following; is :1, :spm'iiir-utiou.

llur invention relates to fuel let-ding in pressure in the rotugu'ossiou (lttlllllltl durmy; the time the inlet port of the urhndor is open.

{Fur invention further (ousists in :1 two i' 13h engine provided with u rotnprvssion rituuiher :t-lltl s l'uvl ret-t-ptzn'lv. the zuuouut 1 of fuel in the rrretit zu'lv livi kept |)t';t(llwill ronsLn-nt, and the tlnountol luvl possroin the rt oegitzu'lv depending upon the l'illt'4 in the nu pressure in the luvl H- I :urle :tud ut. the llll(l portol the \'llll(l'l'.

sure in the fuel ret'zeptucle will always be the some as the air pressure in the crank case. i

' Extending from the receptacle is u matinee-f t'ion 19 terminating in a nozzle 20 which is adapted to be screwed into a threaded opening in the well of the passage 9. The location of this opening depends upon. the fuel employed, and for such fuels us are easily volatilizvd, the position of the nozzleZO relative to the portv it) is not material, but-for 1 surh fuels us do not volatilize easily, the 1102:-

' vertical phtno as shown in Fig. 1 may be bent in any other nutnuer desired. In Fig. 2 it is shown adopted to reeeivv it horizontal needle valve stem 22. The other pan-ts remain as hrlorv. l i The operation of this mechanism is as follows. Through the operation of the float 14 the fuel remains nrurticully at" the leve1-indirut ed hygthv line A in Fig. l. As there is n pnrtinl voi-uuiniu the compressionChamber during enrh ronnn'bssion stroke of the piston, the fuel will rendily flow into the rei-eptuele l l and rtunnin at proper height. During the working stroke of the piston. pressure will he generated in the compression rlnunher and in therw-oiitttelv' ll, hut the valve 13 will prevent the fuel [lowing hut-k. So long ns the port 10 is closed hy the piston, the pressure i on the fuel in the uozzletZO will he the stunt RLS 1n the receptacle 1], and horztuse ol the small size of the passage. hardly ntorv than a. few

llut at the 0nd of the working stroke, when the port 10 is'openvd, the pressure :1 t this point, and the pressure in the. passage 4) also, will he less thiut the pressure in the compression ehiunhor and in the roreptnrlc l t. The result is a. free disehnrge of fuel from the nozzle 30. llczwy oil will hill on the piston and permit the air in the crank (use to smvonge the ('yl- 'intlerbeforeevzuioruting. While the pressu-r in the compression eluunlr-er falls during the entire time the port.1( is open, there IS,

HQSSUIG enove that in the l to flow of fuel wili be in the average of this excess of vwcesure 'ihe inexirnum of this-flow "will end upon'tu needle valve 2i, but the in. the compression chamber will regefte the ilow of the fuel. As this pressure reenhrtee the enxonrit oi air passinginto the cyiii ,this construction will. insn re cq uni proportions of iuel and air, the en'munt of air being regulated. by the valve 8 mid the. amount oi incl depending upon the muount of c 7, the Valve 8 will regulate the power e engine, As before stated, the needle 1 must first lee adjusted according to sto nt ressure in the fuel chain 'cr euse increased amounts of fuel to oner the cylinder, och stroke, with decreased speed. Vi ith this engine there is o discharge of fuel only when the port 10 is open end While there excess of pressure in the crank case. With slow" speed, this eX- ceases as quickly as with higi'a speed, and re slow sneer-i caused by lack ofnir the flow of fuel stops niso.

' Having now explained-coir imprW-xements, ,ct we claim as our invention and desire to .nore by Letters Patent is:

.l. in an explosion. engine, the combinetien of a cyiii'ider and piston therein, a crank car-1e, snid cylinder and crank connected 1:. oort, e valve to control, the admission of crank one a, liquid fuel receptacle, er connection to admit fuel into the receptm eie, VitiVL to prevent a return flow of the Hoot valve to control the height z-rnd Luci) lly constant levelo'f the incl in. the receptacle, a pipe connecting said receptacle and crankcase whereby the two ere'in/constont coinrmmication, and a connection between the fuel receptacle and the inlet port of the cylinder, including alvalve to reguiete the maximum flow of the fuel.

2. In. on explosion engine, the combination of a cylinder having an intake ort, an compression chamber connected to the cylinder by means oi said port, a l'uel receptncle in constant communication with the eir coinpreesion chamber, ueens for automaticeiiy feeding liquid iu el to the receptacle and keeping snbstun tially a constant level therein,

it veive to prevent return flow oi" the fuel, in ,a to control the admission of air to the cc ,yre 'on chamber, and a connection bcl tween the fuel receptacle and the intake port of the cylinder whereby l'ucl may pose to the 1 cylinder, the rate of flow being in proportion to the difl'erence in pressure in the compression chamber and at the discharge end ol said connection.

3. in an explosion engine, the combination of u cylinder, an :nr compression chember connected to the cylinder by u port, a piston in said cylinc'ler adapted to open. :Lihl close said port, it 'l'ucl receptacle, means tor automatically sup )lying fuel to the receptocle and keeping); suhstentielly :i constant lm el therein, a connection whereby the compression chamber and fuel receptacle iLl'O in constant coinmunication, and u l'uel pipe lc:rding from the fuel rcceptuclc lo the port of the cylinder, through which the tool is led.
